Hornet’s “request access to this user’s hidden photos” mechanism leads to an interesting take on hitting on a guy: if he accepts, you know he likes you; if he refuses, there’s not much rejection pain — you can just tell yourself he thought your request was too forward.
And if you don’t like what you see, you don’t even really have to say anything polite, since you never exchanged any actual words with the guy in the first place.
It’s like someone invented the best possible online version of groping someone in a backroom.
